The U's will face Charlton Athletic at home in the Third Round of the FA Cup.
While disappointing, it's a winnable tie, with the Addicks currently residing in the relegation places in the Championship.
What is pretty much guaranteed is Second Round hero Callum Harriott will not feature in the game, because he'll be cup tied if he returns to the Valley at the end of his loan, and Charlton won't let him play for us against them if he extends his loan.
The fixture is likely to be played on Saturday 9th January 2016, unless it's moved for TV coverage (which is extremely unlikely).
